Gallium3D LLVMpipe Compared To Nine Graphics Cards

Phoronix: Gallium3D LLVMpipe Compared To Nine Graphics Cards

Yesterday after publishing the 15-way open-source vs. closed-source NVIDIA/AMD Linux graphics comparison there were some requests by Phoronix readers to also show how the LLVMpipe software rasterizer performance is in reference. For this article to end out the month are the OpenGL performance results from nine lower-end AMD Radeon and NVIDIA GeForce graphics cards running with their respective Mesa/Gallium3D drivers compared to the LLVMpipe software driver in two configurations.

1) Benchmark it doing something that it would actually be useful doing, like DESKTOP COMPOSITING.
2) Benchmark it on a system typical of those that don't already have decent GPU's, like... intel Z520.

Nobody cares how fast it can play games on a very fast 8-core processor.

Well if it can't run OpenErena 8.5 at more then a handful of FPS even on a very fast CPU then any CPU that you have that would not have a supported GPU on the mobo would run compositing over LLVM at around 1 frame every 4 seconds or less.

LLVM is not a substitute for a GPU in any case save for doing single frame rending accuracy tests.

Well, without knowing that much about OpenGL rendering I'm still interested in how it would perform on the Parallella with 64 of those cores: http://www.adapteva.com/products/sil...vices/e64g401/ and whether the latency could be acceptable. (with necessary modifications of course)

The performance would probably not be too impressive, but it could still be ok. Also, 2014 they want to reach for ~1.2 TFlops

Likely wont be that great since they will hit the same wall that Intel did with Larrabee. It might be decent for ray tracing, but probably be terrible for standard graphics and will draw much more power then a dedicated GPU would to do the same task.
